In a Ruby file, when I press command-R to run, about half the time I get an error indicating that we tried to compile as an Xcode project and we are not an Xcode project. Why is TextMate doing this and how can I prevent it? The language thingy at the bottom says it's Ruby so clearly someone in there knows it is; it just doesn't seem to be the same guy who responds to command-R. Thx. m.
